The only patch that touched blk_rq_map_sg() that calls sg_next()
was this:
commit 67e69d5220c904238f94bb2e6001d7c590f5a0bb
Author: Linus Walleij <linus.wall...@linaro.org>
Date: Fri May 19 15:37:27 2017 +0200
mmc: block: remove req back pointer
Just as we can use blk_mq_rq_from_pdu() to get the per-request
tag we can use blk_mq_rq_to_pdu() to get a request from a tag.
Introduce a static inline helper so we are on the clear what
is happening.

Can you try reverting it and see if the problem goes away?
Yours,
